Workflow Description Language; used to specify data processing and analysis workflows with a human-readable and -writeable syntax.

The WDL language is stewarded by the OpenWDL community as described at

Core WDL goals:

  • Make it straightforward to define analysis tasks, chain them together in workflows, and parallelize their execution.
  • Achieve portability not only across execution platforms, but also different types of users. Whether one is an analyst, a programmer, an operator of a production system, or any other sort of user, WDL should be accessible and understandable.
